Walking speed may be a potential indicator for persons with diabetes to identify peak plantar pressure (PPP) distribution during barefoot walking in a diabetic foot. However, the diabetic group demonstrated a more cautious walking pattern than the age–gender matched group by decreasing cadence, step length and anterior–posterior excursion (APE), and increasing step time and toe in/out angle. People with diabetes may reduce the risk of foot ulcerations as long as they are able to prevent severe foot deformities such as callus, hammer toe or charcot foot.
